Walter or Walther of Aquitaine is a king of the Visigoths in Germanic heroic legend.

Epic poetry

Walter figures in several epic poems and narratives dealing with Germanic heroic legend in medieval languages: The most complete poem specifically about Walter is Waltharius, in which Walter fights single-handedly against the Burgundian king Gunther and his retinue, killing all attackers except for Gunther and Hagen. In later literature, Walter figures in Scheffel's novel Ekkehard (1855). Walter is not a historical king, but the historical nucleus of his legend lies in the 5th century (the reign of the Balti dynasty), after king Wallia established a Visigothic kingdom in Aquitaine in 417, clashing with the Vandals under king Gunderic. The Burgundians became neighbours of the Visigoths after being resettled to Savoy by Flavius Aëtius in 443 during the rule of Gunderic of Burgundy.
